Bleeding the clutch is similar to bleeding brakes. You'd pump the clutch pedal several times to get the pressure up, and then open the bleeder on the slave cylinder (mounted down on the transmission). Repeat and add fluid as needed until no air comes out.

Two things - first off, some cars have more than one bleed point (the Nissan 300ZX is one of those), so be sure there is only the slave cylinder to bleed. Second, if it went right to the floor, something failed - either the slave cylinder or the master cylinder. Changing the slave is relatively easy - usually two bolts and it comes off, you put on a new one, and bleed it as described above. Often the slave cylinder is less than $30, so it's worth it to try changing it if you can't get the pedal to come back off the floor on its own. A clutch master is significantly more expensive and more difficult to change, so start cheap and easy and replace the slave cylinder if you can't pump the pedal to get pressure built up for a bleed.

Could be a couple of different things.
1) your clutch master has a plugged pressure bypass, and it is sending excessive pressure to the slave and blowing it out.
2) The clutch throw out arm is bound, and will not allow the slave to compress it.
3) The replacement slave was defective.

if you loosten the slave bleeder screw and push in the clutch pedal fluid should come out if not make sure someone holds down the pedal and tighten the screw then pump the clutch a few times and hold the pedal and open the screw if no fluid repeat a couple of times if still no fluid you need either a new master cylinder or just rebuild it( normally cheaper) and if you rebuild it make sure you flush all the lines of debris

i think youre doing the right thing. they are very stubborn to bleed because the hyd. line goes up high across back of engine before droppiing back down to slave cyl., trapping air. could try to gravity bleed by opening bleeder at slave, cap off of master cyl, full with fluid then it may start to come out after a bit. then try your process again. or can try to bleed at connections further up the line, working your way back to bleeder. hope this helps. be patient.

Start by getting in and working the clutch till your leg feels like its going to fall off.Then hold on floor and have another person open the bleeder.Try this several times...It should build pressure. Hope this helps

Check your hydraulic clutch slave cylinder on the transmission for leakage and check the reservoir fluid level. If the reservoir has run low, you may have air in the lines. If the slave is leaking, replace the slave and bleed the system. Let me know if you need instructions or have more questions.

you need to find the clutch slave cylinder ,make sure the clutch reservoir is full, get somebody to push the clutch pedal in & hold it in while you undo the bleed nipple of the slave cylinder to let any air out ,then tighten it up while the clutch pedal is still pushed down,then release the clutch pedal, keep doing this until only fluid is coming out & no air is in the line.....hope this helps.....cheers

Probably not. Bleeding clutch slave cylinders is tricky because you cant "pump it up". The master cylinder has no static valve so the best way to bleed the slave cyl. is to use gravity. Fill the master cylinder reservoir and open the bleed valve on the slave cyl. Allow fluid to drip into an open can until there's no trace of air. Close bleed valve and try clutch. If still no pedal, repeat the process. This is quite an acceptable procedure.

This is what I would do.Fill the master with brake fluid.Make sure the slave cylinder bleeder is closed.Have someone pump the clutch pedal fully down and while allowing it to come fully up about 20 times and then hold down.Now with the clutch held down ........open the bleeder and hopefully some air will come out.Repeat until fluid appears with out air. The clutch master cylinder piston must be allowed to come fully back in it's cylinder to take in a new load of brake fluid with every pump and in normal operation.Another way to bleed it......is to vacuum the fluid through the system from the master cylinder .......connecting to the slave cylinder bleeder valve.

Should be a bleeder on the slave cylinder. remove the cover on the master and open the slave and let drip until fluid drops sdteady and no sign of air. Close slave and close master after replenishing the fluid. The first time you press on the pedal go slow and release real slow. Then you are off and clutching. Good Luck
